APPARATUS FOR THE PRODUCTION OF OZONE.

To all whom it may concern Be it known that I. JAN S'lEYNl.S. z1-5l1b* of the Queen of the Netherlands. residing at Bay Shore, in the county of Sui folk, State of New York, have invented certain newand useful Improvements in Apparatus for the Production of ()zone, oi? Which the following is a full, clear, and co1nplete disclosure.

My invention relates to apparatus fol the production of ozone ot" the kind wherein a current of air is passed through silent or I of tubes in.

. mulm ger of moisture QlitlllCTOL enters the apparatus. 1

streaming electrical discharges The object of my invention is to produce an ozone apparatus adapted to carry outthe process of making ozone described in my Patent X0. .)ti,l(3c5, \vhichwill be relatirely small and compact and which will require a minimum amount of attention and in which the electrodes may be easily and quickly removed and inserted. I

A further object is to so arrange and dispose the high-tension electrical conductor leading to said apparatus that there will be collecting at the point where and that the attendants cannot accidentally come in contact therewith.

'In the drawings accompanying and t'orni-' ing a part of this specification, I have illus trated one embodiment of my lnvention.

In these drawings l igure 1 is a vertical.

section, and Fig. is a top plan view with portions of the casing: lnoken'away, to show the interior of the a 'iparatus. I

In these drawings the same reference numerals are used in both views to designate the same parts. The apparatus is provided 1th u hcat insulating case 1. 111' which. near the top thereof. there is disposed an air chamber 2. A second chamber 8 is located at the bottom of the insulating case. and the two chambers are connected by a plurality I have illustrated four of these -.'ibes. although it is obvious that the numbe. may be varied within widen limits. Each of these tubes is provided with a cooliug jacket 5 adapted to receive .a cooling agent. such as ammonia gas. These jackets are connected in series. as shown in Fig.2. so that the cooling medium may enter the apparatus by the conduit t. and after passing through all of the jackets in succession. be carried avayby-the conduit 7. Suitable valves may be provided in these conduits 6 Specification of Letters Patent.

be regulated by the attendant, and a uniform ten'ipcrature maintained in the apparatus. .lnside of each of the tubes l there is placed a dielectric tube 8 extending throughout-the tube and slidably fitting therein, so that it. may readily be withdrawn. inside of these dielectric tubes there are disposed electrodes-9, in the form oi elongated rods each having a series of rings 10 thereon. These electrodes are supported by spiders 20, one at eachend of the dielectric tubes, and the arrangement is such that the dielectric tubes and the electrodes therein may be withdrawn vertically through the obser'va tion windows 11, one of which is located above each of the tubes. at their lower ends rest on contacts 12 mounted on an insplated metallic plate 13 energized by means of the high-tension conductor 14: which extends up through the conduit 15 which isclo'sed at its upper end by the insulator 16. The air to be ozonized enters the upper chalnber 2 through the pipe 17, from which chamber it passes down through the tubes 4 into the lower chamber 3 and out by way of the pipe 18. The silent discharges take place from the rings 10 on the electrodes 9 to the tubes l, the latter constituting the other electrodes.

The. entire apparatus is grounded, with the exception of the inner electrodes 9 and the conductor and contacts which supply the current to those parts.

In the operation of the apparatus the air. as it passes each of the rings 10, is progressively ozonized, 'and the heat which is imparted to the air. as it passes each dif these rings is immediately extracted by the coo-ling etlect of the jackets, so that the method of progressively ozonizing and cool ing the treated gas step by step. described in my prior patent, is realized in the operation of this apparatus. serred'that a discharge pipe 18 for conducting away the treated gas, leaves the conduit 15 some distance below its upper end, so that the upper end of this conduit Will contain a dead air chamber, and since the insulator 1.6 closes the top of the dead air chamber, and the temperature of the as or air in this chamber is not apprecia ly lower than that of the surrounding atmosphere. the liability of moisture collecting on the insulator and grounding the high The electrodes 9' It will'be ob- 7 Patented An. 13, 1912.

' tension conductor is excluded. The conduit is extehded to such a'height abovethe apparatus as-"t'o place "the high-tension conductor out of the reach of attendants, and this, arrangement therefore not only prevents the accumulationof moisture and the grounding of the high-tension conductor,

but serves the additionaltpurpose of a protect-ion for the attendants. a

The operation of my improved apparatus may readily-be understood from the foregoing description.

- Airpreviouslydried is admitted by the pipe 17-'and. the'cooling medium by the pipe 6.. The temperature of the cooling medium is so' regulated that no moisture will be,-

- to dothis, it is only necessary to draw the dielectric tubes, and the electrodes supported thereon, upwardly,= there being no screws or nuts or fastenings holding these tubes in position. The parts may then berepaired or new dielectric'tubes and electrodes inserted.

While I hate described only one embodiment of my invention, I am aware that the detailsthereof may be varied without departing from the spirit or scope of my invention.
